Some Votes on the Teritiary Fossils of California. 85 
indurated sandstone was passed through, in which was found 
casts of various shells, together with a few well preserved fossil 
shells. ; 
At a greater depth, from 140 to 160 feet, came a rich variety of 
well preserved shells imbedded in a usually rather soft matrix, 
composed of loosely aggregated grains of sand or fine sandy mud, 
occasionally hardened by infiltration of lime-bearing water. 
The following is a list of the species obtained from this well by 
Mr. Hemphill, as they were identified and published in the Pro- 
ceedings of the California Academy of Sciences, Vol. V, pp.
